Evaluation of speech quality is a key component of any audio application involving voice communications including telecommunications, consumer electronics and hearing assistance. Objective intrusive speech quality assessment is widely used to evaluate speech quality from various speech processing tasks such as speech enhancement [1]}, [2]}, dereverbration [3]} and speech synthesis [4]}. Perceptual Evaluation of Speech Quality (PESQ) [5]} is designed to test the speech and voice quality of speech as perceived by human beings. Short-Time Objective Intelligibility (STOI) [6]} focuses more on intelligibility measurement. Hearing-Aid Speech Quality Index (HASQI) [7]} is a method created specifically to evaluate speech quality for hearing aid users.
